Abstract
An apparatus for the magnetic inspection of ferrous conduit for signs of wear includes a housing having a first end, a second end and a conduit travel passage extending through the housing from the first end to the second end. At least one coil is positioned within the housing encircling the conduit travel passage. The coil is disposed at an angle to the conduit travel passage so as to create a transverse flux component. Sensor supports are positioned along the conduit travel passage encircled by the coil. At least one sensor array is mounted on the sensor supports. The sensor array is oriented to detect flux patterns which extend transversely relative to the conduit travel passage. A computer is in communication with the sensor array to receive and interpret signals from the sensor array.
